Summary
Definition
History and exam
Key diagnostic factors
- positive family history of epidermolysis bullosa (EB)
- mechanical fragility of the skin
- recurrent blisters and erosions
- poorly healing wounds
- onset of cutaneous signs at birth or early infancy
- resolution of blistering within the first 1-2 years of life
- generalized or localized distribution of skin involvement
- combination of milia, scarring, and dystrophic nails
- absence of milia, scarring, and dystrophic nails
- exuberant granulation tissue
- herpetiform blistering
- pseudosyndactyly
- enamel hypoplasia
- reticulate hyperpigmentation
- muscular dystrophy
- tracheolaryngeal stenosis or stricture
- severe upper airway disease
- onset in mid or late childhood
- inverse (intertriginous), acral, or centripetal distribution of skin involvement
- severe cardiomyopathy
Risk factors
- Family history of EB
Diagnostic tests
